Application filed April 29, 1920. Serial No.

To; all whom it mag concern: v

Be it known that I, LOUIS E. BALTZLEY, E|, citizen of the United States of America, and a resident of Glen Ridge, Essex count and State of New Jersey, have invented certain new and useful Improvements in Binders,

of which the following is a specification.

This invention relates to What are commonly known as temporarybinders and the general objects of the-invention are to pro- .vide a device of this" character of simple,

practical construction, which will' 'firmly grip and hold the papers or other articles to be retained, which can be quickly and easily operated to grip or to release the in serted articles, which will hold equally as well a few or a large number of articlesand which, possessing theabove advantages, will consist of but relatively few, simple and durable parts, be relatively inexpensive as to cost and be neat and attractive as to appearance. M

These and other objects I have attained by a novel construction and relation of ele-' ments, involving in part, a pair of cooperating clamping jaws having rounded back portions which slide over each other to. produce the jaw opening and closing movements and which are actuated 'forthis purpose by a sliding control membercarrying a pin or pins working in relatively inclined and intersecting slots formed on said backiportionsl Other novel and advantageous featuresof the inventionwill appear as the specification proceeds. Z V

In the accompanying drawing-forming a part of thisspecification l have illustrated the inventionjembodiedinua number of commercial' forms, but wish it understood that the invention may be applied to other-uses than the ones disclosed and further, that the structure may be modified to suit various requirements, as will be'clear from the scope of the appended'claims.

In the drawing referred to 1 Figure 1 is a perspective-view of I the binder' cjonstructed as a clip-for holding loose papers and with the sliding back portionof one of the clamping. jaws shown as partly broken away to better illustrate the intersectingslots. f If l f,"

of this latter construction, with the cover indicated-in dotted lines as. folded back to give complete access to the binder. 1 Fig. 7 is a broken perspective view of the lnventlon as used as a clamp for a drawing board. s o g The jaw elements of the binder are designated 10 and 11 and these are provided, as possibly sliding curved back portions 12fand 13, arrangedpreferably on substantially concentrio arcs and with the concave face at the back'of the clamp; Each jaw furthermore is shown as standing at an acute angle with respect to the normal plane of the curved back, as represented by a line 1 1, joining the opposite edgesof the curvature in the back. This construction enables the forward edges of the; jaw to securely grip the inserted papers, even when the clamp is opened-to the fullest extentgas indicated in Fig. 3.

The curved backmembers of the two jaws are retained in their sliding relation and are heldagainst relative longitudinal displacement bymeans consisting in the illustration of curved guards 15 at the ends of the inner back member 13, and indicated as formed integrally therewith and as bent in- Patented Aug. 16), 1921.

corresponds to the planes perspective view of this con- ,1

best shown in Fig. .3, with over wardlyin the form of loops, so as to overlap portions of the outer back mem closure, to accomplish the opening and closing movements of the jaws, from a finger slide 16 longitudinally slidable over the outer back member 12 and carrying near its opposite ends the operating pins 17, work: ing in the relatively inclined slots 18 and 19,

formed on intersecting angles in the outer and inner back members. I

This intersecting or crossed relation ofthe slots is particularly shown in Fig. 2, from which view it will be apparent that when the operating pins 17 are "shifted toward the a relatively intersecting slots.

further overla 3 36d or telesco Jed to brin V 2:! the aws together and that the reverse movement of the operating pins will slide the back members in a way to separate or open the jaws.

It will also be clear from Fig. 2 that there may be one, or a number of these pairs of It is desirable to have at least two pairs and therefore, two operating pins, since by this construction the operating slide can be entirely support; ed by the ping-which. as indicated in Fig. 8, be headed over at their'inner ends as at 20, to prevent disengagement from the slots. 1 This latter view also shows how the sliding o'per ating plate preferably is curved to fit the concavity of the outer back member, so as to seat therein and take up very small space at theback of the clamp;

Reverting to Fig. 2, attention is directed to the fact that the slots 18 in the" outer back member and the slots 19 in the inner back member are in each case substantially parallel, and further, that the operating pins 17 are substantially diamond shaped in cross section, having diagonally opposite substantially parallel faces to fit the reverse inclines of these slots. These structural features retain the jaws substantially parallel and cause them to travel in substantial par-' allelism in both-opening and closing movements.

The operating slide is provided with a convenient handle or handles for operating the same, In the first form of the invention, I-have illustrated the same in" the form of rearwardly or outwardly projecting lugs 21 integrally formed at the opposite ends of the slide and for convenience in operation, I have shown one of the back members, the inner one 13 in this instance, as provided with similar rearwardly projecting lugs 22, so that the slide may beactuated in opposite directions by a pinching engagement of the fingers with the pair of lugs 2122 atone or the other end of the clamp. This construction enables the necessary force to be easily applied, without shaking the clamp or disarranging the papers inserted therein.

a The relatively XGCl grips 22 also may be so located as to form stopslimiting the movement of the slide in opposite directions.

From the description thus far, it will be apparent that the clamp may be quickly opened'or closed by simply exerting a pinching force on the cooperating pairs of grips 21 22 provided at theopposite ends thereof. The crossed. slots are arranged on rel.- atively slight inclines to the horizontal 2) so that the pins or lugs working therein will securely hold the aws in any position to which they have been set. The jaws are usually constructed of resilient or spring material and this feature also aids materially in maintaining the jaws in the position to which they have been adjusted, since as the aws yield more or less, the parts are caused to bind and hold all the more In the first two forms I have shown the binder as used simply as clip for loose papers or the like.

In Figs. 3 and 4;, the binder is shown as permanently secured to a backing or board 23, as by means of tubular rivets 24: passed through the lower jaw 11 and secured in the material of the board. This provides a very the cover is turned back as indicated in dotted lines in Fig. 6. In this construction, the binder has all the appearance of an ordinary book'a'nd possesses addition the advantages of quick operating temporary binder. 7

Another possible use of the invention is disclosed in Fig. 7, wherein I have shown the under jaw of the clamp as secured by suitable fastenings 28 in a recess 29 in the edge of a drawing board 30", the upper clamping jaw 10 being exposed siibstanti'a'lly flush with the face of the board for the purpose of clamping a sheet of drawing paper. In this view also I have shown how the operating slide may have only a single grip or finger hold 21*";

In addition to the advantages enumerated, the invention has the further important advantage that all the main parts may be constructed of sheet netal and are of such construction that they may be produced by simple stamping operations. The construction, furthermore, it will be seen, provides a particularly wide-opening clamp which enables loose papers to be very readily engaged therein.

This wide-opening feature is particularly shown in Fig. 3 where, in thedo'tted lines, it will be noted that the binder will open up to the full height of the expanded back, or to a point where'the jaws stand substantially parallel, the sliding back members being so designed as to stand in overlapping relation even in this' fully expanded condi tion. view, the curved backs of the jaws are drawn on arcs from a center located to the rear of the binder, say at the point 31, from which it follows that the clamping edge ofthe jaw or jaws traverse a wider angle than the relatively movable backs.
